16 And said, By myself have I sworn, said the LORD, for because you have done this thing, and have not withheld your son, your only son:

17 That in blessing I will bless you, and in multiplying I will multiply your seed as the stars of the heaven, and as the sand which is on the sea shore; and your seed shall possess the gate of his enemies;

18 And in your seed shall all the nations of the earth be blessed; because you have obeyed my voice.
